Our hot water heater installation services include conventional tank systems as well as tankless hot water heaters. Allow US Plumbing and Gas LLC to provide a free quote for removing and installing a new hot water heater. Usually a water tank will leak right after the warranty expires! Check the label and see how old your hot water tank is. If you have a standard 6 year warranty, and you are on your 7th year, don’t wait. If you are experiencing rust at the bottom, condensation, or lack of readily available hot water, the tank is about to fail.
